[Fix] The Selected Disk Has an MBR Partition Table – TechDim

The selected disk has an MBR partition table is a common error message in windows just like Windows cannot be installed on this disk because it has an MBR partition. This error occurs when the user tries to install Windows operating system on their computer. This error happens when the partition table doesn’t support the installation process. If there is an EFI system in your device, the windows can only be installed on a GPT disk drive. If you have an MBR partition table, the installation process can’t be possible. And, when the error message occurs, you can’t complete the installation operation until you fix the issue mentioned just like an issue like the selected disk is of a GPT partition style.

For this, you can fix the error by either change the BIOS settings or change the MBR disk to a GPT disk. You have to go to the BIOS settings of your computer and change the EFI system to legacy mood.
